[0002] Pulp processing and crushing is a core step in the pulp and paper industry. Its purpose is to break down raw materials (such as wood, waste paper, and non-wood fibers) into fiber bundles or individual fibers through physical or chemical methods, while controlling fiber length, fineness, and degree of damage to meet the quality requirements of different paper products (such as cultural paper, packaging paper, and specialty paper). Physical pulping and crushing are mostly carried out using a refiner, where the material is crushed by shear force between a high-speed rotating grinding disc and a stationary grinding disc, resulting in fiber bundles.

The refiner crushes the materials by shearing force between the high-speed rotating grinding disc and the fixed grinding disc, outputting fiber bundles. This feeding method prevents material splashing and provides high protection.

[0015] The present invention describes a pulp crushing device that uses a servo motor controller to automatically control the speed of the servo motor, thereby controlling the feeding rate. The control valve is opened, and hot steam generated by the steam generator is transported to the pulp mill through the steam conveying pipe.
